Hi,
After downgrading my plc (7" UniStream) from UniLogic 1.23.25 to Unilogic 1.18.60 i got this error.
I have tried to upgrade it to Unilogic 1.23.25 again but nothing helps.
Here is an image of the error message:
Please help.
Thanks in advance.

For information.
We have 2 systems with identical programs, both of which have the same problem.
System 1: new PLS and new SD card.
System 2: Was updated from 1.18.60 to 1.22.13 to 1.23.25,
At version 1.22.13, I enabled SD management to keep the last 32 files.
After I encountered HMI Overload problems, I updated to 1.23.25 and deleted manually the sample files, but left 20 old files on the system.
I added some sample files in the attachment.
Samples Invalid Date.zip

That's good
I also had SD Management configured before updating.
But now i got a new problem. After updating to version 1.23.25 the trend viewer says "invalid date".
This means that the file does not gets saved with the date as the name, but rather a increased number to the last filename.
I'm waiting for response from Unitronics.

Here is the feedback i got from Unitronics: "The 'HMI overload' screen you received is the consequence of loading a data sampler that its directory on the SD contains several hundreds of files.
Note: when you loading a data sampler the PLC scans all the files in its directory on the SD, and in case there are too many it can cause an HMI overload.
There are 2 ways I would like to suggest you:
* In the newer versions of UniLogic, there is a feature called "SD management" – There you can define the maximal number of files stored for each feature.
When the number of files exceeds the defined limit , it will automatically delete 1/8 of the oldest files."
I updated to the newest version (1.23.25) and deleted the files, now everyting works

Hi.
I found where the backup files were saved, i got error code 0x80070718.
The problem was that the limit on cash on offline files was full, i increased the limit and everything works

I know its old, but i there is to many problems with CUP error and HMI overload with the newest update.
Anyone that know why this happends?
Thanks in advance.

Hi,
I have updated to the new version UniLogic 1.22.13, and i have a problem. When opening a page with an Trend viewe i get an error message, "HMI Overload".
The program was an updated from UniLogic 1.18.60 to UniLogic 1.22.13.
Fix?

Hi Dan.
This i know,
But then it should be informed that this corner cannot be used to have buttons and other touch elements in it.
We had a problem with this when we sent a project with an button in this coner,
I have now tested this on the 7" display too, and the same problem.
Thanks.

Hi.
I have found a problem with the 10" UniStream panel.
If you set in an element in the corner, it will not work.
I have tried this with 5 more displays, so this is not an coincidence.
When will this be fixed?
